Injection Molding
for Various Industries
From automotive interiors to medical device housings, SANGO molds parts to the tolerances and material specs each industry actually requires — not a one-size-fits-all process.Injection Molding Quality Control
Quality gets built in at mold design, not inspected in at the end. Cross-team DFM reviews and in-process controls hold first-pass yield at 90% or better across every production run.
Frequently Asked Questions
We run injection molding directly - our own process engineers review your design, our own tooling shop builds and maintains the mold, and our own press floor runs production. There's no broker relaying files between you and a third-party shop, which means design feedback, DFM changes, and quality issues get resolved in one conversation instead of passing through a middleman.

Plastic Injection Molding Services for Custom Parts
SANGO takes your part from a handful of prototype units to full production runs on the same tooling philosophy, with T1 samples ready in as fast as 2 weeks. Our China-based facilities run 90 to 830-ton presses, so small precision components and large structural housings both stay in-house.
Precision mold tooling, overmolding, and insert molding all run through the same DFM review before steel is cut, so bond compatibility and wall thickness are checked once rather than per process. One partner across design, tooling, and production means fewer handoffs, tighter part consistency, and a clearer path to scaling volume.
